End Google Ads 201810 - BS.net 01 --> In 8 bits bitmap, i learn that it has a color table in the file and the region

of bitmap data are indexes of the array. I want to get a part of image from the

orignal 8 bits bitmap, but i don't know the relation between bitmap data and

color table.

If someone know it, please tell me.

you may send it to my email.my email is: shuhua_song@sina.com

Thank you very much!
